Behind Stimulus Argument, Debate on Causes of Joblessness Grows

This article provides two arguements for the continued high rate of unemployment. One of the arguements goes along with the standard reasoning behind unemployment. Demand is down, people are not spending money, businesses are not growing and investing. The other arguement is a little more interesting. Unemployment can be curved if people could figure out a way to sell their house and move to where to work is. If this is the case, is there anything the government can do to fix this disparity or will the job market just have to take care of itself?
